Fluid induction device



Sept. l5, 1931. A Y G. E. MAIER I FLUID INDUCTION DEVICE Filed Aug. 21,1926 INVENTOR GEORGEYE. MAIER Patented Sept. 15, 1931 UNITED STATESGEORG-E E. MAIER, OF LOS ANGELES, CALIFORNIA FLUID INDUCTION DEVICEApplication filed August 21, 1926. Serial No. 130,571.

My invention relates to improvements in fluid induction devices, andmore particularly to fluid feeding means for containers, suoli asboilers.

5 Among the objects of my invention is to provide means for producing arapid circulation in the fluid content of a container and to employ suchcirculation in the feeding of a supply fluid to the container.

A further object is to provide a fluid container with a fluid supplymeans comprising a fluid course defining means in open communicationwith the content of the container; means for promoting a rapid movement15 of the fluid in the course defining means, and an inductor connectedwith a source of fluid supply and located in the line of said coursedefining means whereby the feeding of a supply iiuid is accomplished bymovement of the content of the container.

A further object is to provide a means whereby the circulation of anormally equalized fluid pressure from a vessel through an inductor andback to the vessel again will induct fluids from various supply sourcesinto the circulating fluid and thence into the vessel and therebyincrease or maintain the pressure and volume of fluid in the vessel tobe used for various supply purposes.

A further object is to provide a device of the above character wherebyexhaust steam will be inducted into a boiler and thereby reclaimconsiderable heat units, by which, a great fuel economy will be affectedand the generation of steam greatly enhanced.

A further object is to provide an appliance of the above nature wherebyfeedwater will be inducted into a boiler by the expenditure of the leastamount of energy.

And a still further object is to provide a mechanism of the above naturewhereby fluid will be inducted into a reservoir and thereby produce avolume and pressure of fluid in the reservoir without the necessity ofexternal compression, by which means the excessive heat due tocompression will be eliminated.

I attain these objects by the mechanism illustrated in the accompanyingdrawing, in which The ligure is a diagrammatical view of the entireapparatus. with the inductor and check valve shown in section.

More specically, l indicates a boiler or reservoir, 2 a lead pipe'fromthe boiler, 3 a fluid circulating machine (centrifugal pump), l anintermediate pipe, 5 the inductor, 5 aninductor nozzle, 5 an inductorintake, 6 a return pipe to boiler, 7 a pipe connecting a check valvewith the inductor, 8 a check valve, 9 a supply pipe to the boiler,'l0 anoperating engine (turbine), ll a fluid supply pipe to the operatingengine, l2 an exhaust pipe from the operating engine, 13 a shaftconnection between operating engine and pump, 14 a supply connectionfrom the boiler.

In carrying out the feature of my invention a vessel l of any suitablecharacter may be employed to which a lead pipe 2 connects the vesselwith a centrifugal pump 3, intermediate pipe l connects the pump 3 withthe inductor 5 and inductor 5 connects to vessel l by means of returnpipe 6, which arrangement completes the circulating units. The turbinel0 operates the centrifugal pump 3. Check valve 8 is provided to preventbacli flow of the fluid from the vessel when the circulation of thefluid through the inductor has been practically stopped.

The operation of the invention is as follows Vessel l containing a Huidunder any pressure freely admits the fluid to the centrifugal pump 3through lead pipe 2, the turbine l0 operates the centrifugal pump 3which forces the fluid from the vessel through the inductor 5 and nozzle5 back into the boiler again through return pipe 6 thus forming acontinuous circulation of fluid through said units. The centrifugal pump3 will force the fluid from the vessel through the inductor nozzle 5 athigh velocity which will produce suflicient vacuum in the inductorintake 5 to aifect induction therein, and thereby induct a fluid intothe vessel from an extraneous source.

In the application of this invention any suitable type of circulatingpump may be employed, such as the centrifugal pump shown; andthecirculating pump may be operated by any suitable operating mechanism,such as the steam turbine shown.

The intake 11 of the engine 10 is connected to the boiler as by pipe 14whereby the iiuid for operating the engine will be taken from theboiler. The exhaust pipe 12 from the operating engine is connected tothe supply pipe 9 and the exhausted uid from the operating engine isinducted back into the boiler, as by pipe 15, through pipe 9, checkvalve 8, pipe 7, inductor 5 and pipe 6.

I claim:-

l. In a device of the character described, Y

the combination of a boiler, a fluid circulating pump having its intakecommunicating with said boiler, an inductor connecting with thedischarge side of said pump and communicating with the boiler, a supplypipe connecting with said inductor, a check valve in said pipe, a steamoperated engine for actuating said pump, means for supplying steam fromsaid boiler to said engine to actuate the latter, and means whereby theexhaust steam from said engine may be returned to said boiler throughsaid supply pipe, check valve and inductor.

2. In a device of the class described, comprising in combination, aboiler, a fluid course defining means having its intake and outlet incommunication with the boiler, a circulating pump connecting with saidfluid course deiining means, an inductor in said fluid course definingmeans on the discharge side of said pump, communicating with a source ofsupply, an engine for operating said pump having an intake connectingwith the steam Zone of said boiler and an outlet communicating withsaidinductor.

In testimony whereof, I have affixed my signature.
